Question

A circle has its center at (−2, 5) and a radius of 4 units. What is the equation of the circle?

(x + 2)2 + (y − 5)2 = 16
(x + 2)2 + (y + 5)2 = 16
(x + 2)2 + (y − 5)2 = 4
(x − 2)2 + (y + 5)2 = 4

Answer 1

@IshipDestiel here u go

Answer 2

not my question i just posted it for @IshipDestiel
